The Blanchard Valley Conference is an Ohio High School Athletic Association affiliated athletic league located in Hancock, Putnam, and Wood Counties in northwest Ohio. Its name derives from the Blanchard River, which runs through the area in which the schools are located. Findlay, which is part of the Northern Lakes League, and Cory-Rawson, which is a part of the Northwest Central Conference, are the only high schools in Hancock County that are a member of the Ohio High School Athletic Association that aren't part of the BVC.
